increase values so that they are longer
than your machinery design values. If
the specified time is short, the inverter
may not run the motor properly.

When accessing the function code P02*, take into account that changing the P02* data automatically updates the data
of the function codes P03*, P06* to P23*, P53* to P56*, and H46.
Tuning procedure
(1) Selection of tuning type
Check the situation of the machinery and select "Tuning with the motor stopped (P04* = 1)" or "Tuning with the motor running
(P04* = 2)." For the latter tuning, adjust the acceleration and deceleration times (F07 and F08) and specify the rotation direction
that matches the actual rotation direction of the machinery.
P04*
data
Tuning type Motor parameters subjected to tuning Tuning
Select under the
following conditions
1
Tune while
the motor
stops
Primary resistance (%R1) (P07*)
Leakage reactance (%X) (P08*)
Rated slip frequency (P12*)
%X correction factor 1 and 2 (P53* and P54*)
Tuning with the motor
stopped.
Cannot rotate the motor.
2
Tune while
the motor is
rotating
under V/f
control
No-load current (P06*)
Primary resistance (%R1) (P07*)
Leakage reactance (%X) (P08*)
Rated slip frequency (P12*)
Magnetic saturation factors 1 to 5
Magnetic saturation extension factors
"a" to "c" (P16* to P23*)
%X correction factor 1 and 2 (P53* and P54*)
Tuning the %R1 and %X,
with the motor stopped.
Tuning the no-load current
and magnetic saturation
factor, with the motor
running at 50% of the base
frequency.
Tuning the rated slip
frequency, with the motor
stopped.
Can rotate the motor,
provided that it is safe.
Note that little load
should be applied
during tuning. Tuning
with load applied
decreases the tuning
accuracy.
The tuning results of motor parameters will be automatically saved into their respective function codes. If P04* tuning is
performed, for instance, the tuning results will be saved into P* codes (Motor 1* parameters).
(2) Preparation of machinery
Perform appropriate preparations on the motor and its load, such as disengaging the coupling from the motor and deactivating
the safety devices.
